Criteria update
PHI building criteria update 2015
• All PHI building energy standards combinedin one document
• Verification according to Renewable Primary Energy (PER) demand and generation(optional)
• Classification as Passive House or EnerPHit Classic, Plus and Premium
• Criteria for all standards applicableworldwide
• Introduction of the new PHI Low EnergyBuilding Standard
• Pre-certification for stepwise retrofit
� In effect for english-speaking users from late 2015

Timeline for EnerPHit Criteria
2010
EnerPHit Standard introduced for residentialbuildings in cool-temperate climates
2012
extended to non-residential buildings andbuildings with interior insulation
Late 2015 (April 2015 for German PHPP)
extended to all climates worldwide,
introduction of EnerPHit classes Classic, Plus, and Premium
Late 2015 (for German and English PHPP)
pre-certification for stepwise retrofit to EnerPHit Standard
